RE: Evolution 45GX will not draw fuel ???
So just before I round file the engine I try another ignition and wham! I have a runner. Several great flights and now I have an another issue, I can turn the H needle out 4 or 5 turns and no change, from 1.5 turns out nothing occurs. I am spinning a 22x8 JXF at 6900 to 7000 But after 10 seconds or so I loose 200 rpm. The exhaust is a Proflow can and I get good transition but the idle is weird, after a run it will drop to 1700 then climb to 2200. My engine has a Walbro 613 on it, is that the correct carb for a first generation 45gx? My reed block is good, and fuel delivery is perfect. Any advice? Crank case leaks?
